Not true about Zika virus,
**Core Concept**
Zika virus is a flavivirus transmitted primarily through the bite of an infected Aedes mosquito, causing a mild febrile illness in most patients. However, its association with congenital abnormalities, particularly microcephaly, has raised significant concern worldwide.
**Why the Correct Answer is Right**
The correct answer will be related to the unique characteristics or transmission dynamics of Zika virus. The virus is primarily spread through the bite of an infected Aedes mosquito, and its transmission can also occur through vertical transmission from mother to fetus, leading to congenital abnormalities.
**Why Each Wrong Option is Incorrect**
**Option A:** Wrong because Zika virus is not primarily spread through ticks or lice. While ticks and lice can transmit other flaviviruses like tick-borne encephalitis and scrub typhus, respectively, Zika virus is specifically associated with the Aedes mosquito.
**Option B:** Wrong because Zika virus is not primarily spread through sexual contact. While sexual transmission has been reported, it is not the primary mode of transmission. The virus is mainly spread through the bite of an infected Aedes mosquito.
**Option C:** Wrong because Zika virus is not primarily spread through contaminated food or water. While the virus can be present in bodily fluids, its primary mode of transmission is through the bite of an infected Aedes mosquito.
**Option D:** Wrong because Zika virus is not primarily spread through contact with infected animals. While some flaviviruses can be transmitted through contact with infected animals, Zika virus is specifically associated with the Aedes mosquito.
**Clinical Pearl / High-Yield Fact**
Zika virus infection during pregnancy can lead to congenital abnormalities, particularly microcephaly, and should be a concern for pregnant women living in or traveling to endemic areas. This highlights the importance of mosquito control measures and prenatal screening for Zika virus.
